For me every file has always showed up when using zoom. I prefer zoom to ftp because although FTP can sometimes be faster, but often it get stuck in the FTP pending folder for very very very long time. Several hours, sometimes almost a day. So zoom is my preferred method.
Besides, if you put in wrong login info, what difference would it make to you if it uploads as anonymous or to a specific account? It won't be into your account regardless, so just make sure your info is correct!
